💅 libnvme(9) — like, the API Manual, bestie 🎀

okay so real talk, this page is from the libnvme API Manual (section 9, we stan a classic) and it's about one very specific little struct. she's small, she's specific, she's iconic in a niche way. let's get into it ✨

---

🌸 NAME 🌸

struct nvme_set_feature_event — the Set Feature Event Data struct, no cap 💖

---

🦋 SYNOPSIS 🦋

here's the whole vibe, verbatim, don't touch:

struct nvme_set_feature_event {
    __le32 layout;
    __le32 cdw_mem[0];
 };

like… that's it. that's the girl. short and to the point 🫶

---

👑 Members 👑

okay so she has exactly two members and both of them are lowkey important so pay attention bestie:

• layout — the Set Feature Event Layout. yes, the field is literally called layout and yes, it does layout things. main character energy fr fr 💅
• cdw_mem — the Command Dwords Memory buffer. a zero-length array, cdw_mem[0], doing that flexible-array-member thing where the memory just lives right after the struct. it's giving "the struct continues past the end of the struct" and honestly? iconic 😭

ngl, cdw_mem[0] is a zero-length array — don't go assuming it holds anything on its own. the actual command dwords memory buffer lives past the end of the struct, iykyk 👀

---

so yeah, that's the whole page. two fields, one struct, zero fluff. ate and left no crumbs 🔥⭐🌈

hope that cleared things up, bestie — go forth and slay your feature events 💜🦋🍓
